Photochemical weathering and eco-corona formation through natural organic matter (NOM) adsorption play vital roles in the aggregation tendencies of nanoplastics (NPs) aquatic environments. However, it remains unclear how photochemical alters patterns NOM conformation eco-corona, subsequently affecting NPs. This study examined effect Suwannee River on kinetics pristine photoaged polystyrene (PS) NPs monovalent electrolyte solutions. The results showed that influenced which, turn, determined NP stability presence NOM. Hydrophobic components predominantly bound to hydrophobic π–π interactions, extended hydrophilic segments water hindered via steric repulsion. Conversely, hydrogen bonding facilitated binding these multiple NPs, thereby destabilizing them polymer bridging. Additionally, stabilization destabilization capacities increased with its concentration molecular weight. These findings shed light role weathered offering new perspectives environmental colloidal chemistry fate complex

Microplastic (MP) pollution, an emerging global change factor, disturbs the ecosystem functioning. Inland wetlands, providing important services, might be sink for MPs. Understanding distribution, source, and fate of MPs in inland wetland ecosystems is a prerequisite developing effective management strategy. Here, different types including river wetland, constructed lake were selected to explore pollution patterns therein. Results showed that abundance soil ranges from 532 4309 items/kg. Transparent, fibers, polyethylene terephthalate most common color, shape, polymer type MPs, respectively. The this study did not significantly remove was one main sinks had accumulated large amounts In addition, MP characteristics cluster analyses aquaculture, agricultural cultivation, domestic waste sources area. occluded particulate organic carbon content related abundance. conclusion, reveals special river-constructed-lake which would help better understand distribution source wetlands have implications subsequent control ecological restoration wetlands.

The aging processes of microplastics (MPs) are prevalent in natural environments. Understanding the mechanisms MPs is crucial for assessing their environmental behavior and potential risks. In this study, we selected polylactic acid (PLA) polyethylene (PE) as representatives biodegradable conventional plastics, respectively, to examine changes physicochemical properties induced by water UV light exposure. Laboratory resulted significant fragmentation, characterized cracks pores on surfaces, both types MPs, with PLA exhibiting more severe changes, particularly under combined Notably, tended become progressively smaller after aging, whereas PE did not show size changes. Chemical analyses aged using micro-Fourier-transform infrared spectroscopy (FTIR) X-ray photoelectron (XPS) revealed a substantial increase carbonyl index (CI) oxygen content PE, suggesting surface oxidation during photo-oxidation. Conversely, displayed CI decrease, along an increase, indicating breakdown ester linkages formation other products. Furthermore, developed optimized pyrolysis–gas chromatography–mass spectrometry (Py–GC–MS) methods identify chemical degradation products PLA, considering differing thermal stabilities. We observed distinct trend regarding peaks chromatogram identified typical crosslinking PLA. Additionally, process, exhibited organic carbon content, eluate containing submicron/nano-sized particles.

Microplastics (MPs) (< 5 mm) are a growing environmental problem and have garnered significant global interest by scientists policy makers. Coastal ecosystems vulnerable to MP pollution, assessing their sources, fate, transport in the environment is imperative for marine ecosystem health. Data sediment still limited, particularly Pearl River Estuary (PRE) China. Here, we assessed abundance, characteristics, risks of MPs sediments from PRE. abundance ranged 2.05 × 103 items ·kg-1 7.75 (dry weight), white black were dominant colors. The majority (> 64.12%) detected <0.85mm primarily consisted pellets (36.84%) fragments (29.65%). Three polymer types identified Fourier Transform Infrared Spectroscopy (FT-IR) including polyethylene (PE), terephthalate (PET), polypropylene (PP). Meanwhile, polyurethane (PU) sponge was reported first time this study area. Observations surface morphology typical using Scanning Electron Microscopy (SEM) showed that all exhibited varying degrees erosion, characterized cracks, folds, bumpy structures. Furthermore, different concentrations heavy metal elements found on surfaces some MPs, potentially adsorbed surrounding environment. Based type quantity polymers identified, classified risk contamination PRE as category III, indicating severe contamination. Results investigation may serve an effective model other estuaries facing similar pollution regimes provides valuable information assessment.
